[Yoda]

Just wondering about the Straight Line Delivery Path (10-23-C). In this video
clip, I really have a hard time identifying the straight line. Keying on
Brian's left hand, there are no three consecutive frames that line up well.
In Brian's new iron swing there is a more noticable straight line. In either
case there is nowhere near the length of straight line motion as illustrated
in the book. Is there room for improvement here or is this typical?

I have reviewed Brian's Driver Stroke -- I now have it on my own computer! --
and agree with you that his Hands may not be taking the Straight Line
Path of 10-23-A. Instead, it may be the Angled Path of 10-23-B, and I
have edited the original post to reflect that conclusion. If it is the Angled
Path -- I would need a down-the-line view to tell for sure -- it would be
compatible with the slight Plane Shift in the Backstroke noted in my original
analysis and would return him to Impact in perfect alignment.

I also agree that the Iron Stroke clip appears to use the Straight Line
Path.

Regarding your question about improving by sustaining the length of the Line
Paths:

It doesn't take much to satisfy the Straight Line requirements of the Line
Paths; a little will do. Then, the Release Trigger (7-20) will
determine how far down the Path you continue to go. This is the 'Pulley Wheel
Encounter' of the Endless Belt Effect (2-K #6).

An early Release Point -- Sweep Release -- means an earlier end to the
Straight Line Delivery Path -- but not the Thrust! -- towards the Aiming
Point (6-E-2) and a 'larger Pulley Wheel.' A later Release Point -- Snap Release
-- means a longer Straight Line Delivery Path and a 'smaller Pulley Wheel.'

The larger the Pulley Wheel, the lower the Clubhead Speed for a
given Belt Speed (Hand Speed). Therefore, to achieve a given Clubhead Speed,
Sweep Releases require a higher Hand Speed than Snap Releases.


In the right Hands -- pun intended! -- both can be equally effective.
